To all whom it may concern: l

Be it known that I, Hmnnrcn KNooH,

manufacturer, a citizeirof the Gerinan Empire, residing at Adlershof, near Berlin, in

the Kingdom of Prussia, Germany, have invented certain. new and useful Improveinents in Tires for-'Automobile-VVheels; and I I do hereby declare the following to be a full, clear, and exact description of the, in-

vention, such as willenable others skilled in the art to which it appertains to make and use the same. My invention relates to improvements in tires for automobile wheels, and more particularly to tires which areparticularly adapted for heavy loads. "And the object of! the improvements is'to provide a tire which is particularly durable, which can be manufactured at lowcost, and which. does not slip on a wet or slippery road.

Uth :these objects in view my invention consists in composing the tire,-of -suitab1y shaped, solid, hardened pieces of wool felt.

Myinvention will be more fully'describcd in connection with the accompanying drawing and will be more particularly pointed out in and by the appended claim.

In the drawings: Figure-l is a planview of one'embodini'ent of my invention wit-h the tire omitted on the left hand Sid:;tl1l60f.

Fig. 2 is a sectional view on line 22 of Fig. 1 with the tire'blocks or 'piocesi1 1 place arcs of the drawings 4 on both sides.

Like characters of reference ,designatesimilar parts throughout the different fig- As shown, the tire is composed of piecesa a of. pure wool felt, which is; hardened and made waterproof in any suitable way, without howeverimpairing its elasticity. The piccesof felt, which may have anypreferred. cross-section, are held together by means of rings 6, and flanged rings 0. The tire which is thus formed of the blocks a, and the rings 7) undo is secured tothe rim d of the wheel,

as is known in the art. v r

TIRE FOR-'AUTOMOBIIiE-WHEELS.;

- Patented Aug. 6,1912. Srial no. 612,298,

In the example shown, which is particva larly deslgnedforuse in freightcars,the-- rim is provided with two tires which are" preferably separated by a filling 0r spacing ring 6. .The latter is preferably made of wood. In cases in which the load-on the wheel is smaller, a single tire will. be sufficient,

To facilitate assembling of the parts, the rin'gs'c may be made in halves or the rings b may be split so as to be sprung over the rings 0; However, 'the rings 6 may be riveted to the channel 0 before the parts are as sembled and the elasticity of the felt blocks a will be sufiicient to pressed into position.

- In accordance with my inventionv it will be noticed that the felt blocks are not wedged into the channels but merely fit the channel's closely and are locked in place by the rings Z It'will thus be seen that I may utilize solid material for the channel 0 as the inner faces are smooth and unbroken and no shoulders or recesses, or other special portions are necessary. 7 By reason of the fact that I do not rely upon a wedge engagement of the blocks with the channels in order to hold the former in place, I thereby avoid the. provision of lining between the felt blocks and the inner facesof'the channel.

I claim herein as my invention:

In a vehicle wheel, the combination of a fe'lly, a tire thereon composed of solid blocks ,provided with laterally disposed grooves therein, rings sunk in said grooves with their outer faces-flush with the outer side faces of said blocks, andmeans fitting the flush sides of said blocks and ringsfor securing the tire to said telly. v,

In testimony whereof I- hereunto aflix my signature in the presence of two witnesses.
